notches iforufreely ,In order that the lnioiinting andoperation n. 'Y

of my improved vehicljejspringmay be accu# rat'ely understood I have, in thedrawings,

shown the device ingconiiection with conf/g ventiona'l typefof motor vehicle. Thelongi-v tudinal side. bars ofgthechassis of the-vehi-l 1 cle are indicated at' 23, the front axle of the vehicle vat 24,'and the rear axle at 25. YAs

will, of course, be understood, a pair of these springs 'are'employed at thehfront end Yof the vehicle and a pair atthe rear thereof.

The arms 10 of the pair of springs at the front of the vehicle are arrangedV alinementwith the frame bars 23 ofthe chassisV Yto project forwardly'therefrom' and are secured at their innerA ends` to said ,bars.;by"

plates 26. Similarly, the arms VlOof the pair ofl springs at the rear of the vehicle :near-,

' ranged in alinement. withl the Vside bars 23 top'roject rearwardlytherefrom and are secured at their inner ends to said-side bars Y by plates 27 corresponding to the plates 26.

The arms 10 of the springsY will thus be'` fixed so that, as will be seen, by connecting thev inner ends of the arms 11 of the front and .rear springs with` the front and rear axlesrespectively, the leaf springs. 17 'and 18 will be flexed for yieldably sustaining the load. Further, it will be seen that owing tothe length of the armsv l1, unusual leverage will be had upon. the leaf springs for accordingly enhancing the easy riding qualities of the vehicle.

' -Extending between the inner end portions of the arms 10 and-11 Vof the front springs of the vehicle are stop Vrods-2.8 formed of freely-connected sections pivotallyl engaged `attheir outer ends withithe arms.

`These rods are thus Aadapted to limit rebound of the arms 1l of the front springs.V Mounted upon the front axlel24 of the vehicle are channel platesl 29 each secured to the'axl'e lby a pair of U- bolts 30. Secured at corresponding end portions thereof within the arms'll of the front springs are spring arms 3 1 extending rearwardly 'toward the front axle and provided at their rear ends with bearings 32. These .bearings fit snugly between the side flanges of the channel plates and receive bolts 33 pivotally connecting the arms 11 of the front springs with the front axle. Secured at corresponding end portions thereto to the rear ends ofthe arms 11 of the rear springs ofthe vehicle are spring arms 34 which 'are bowed beneath the rear axle 25 of the vehicle. Lying beneath this axle are blocks 35 each Vsecured by a pair of U-bolts 36 engaging around the axle and pivotally connecting the free endscf theA arms 34 with said blocks are shackles 37. The rear springs are thus operatively' connected with therear axles of the vehicle and in connection with these rear springs I einvploy stop rods 38 pi-votallyconnected to the arms 10 of said springs and' Afreely received through the arms 11 thereof, being provided.

at their lower ends with'heads 39. f Held by the fastening devices securing the spring arms 34 are cup-s4() and seated in these cups are resilient cushions 41 which maybe formed of rubber. As particularly illustrated in. Fig.j2,the rods 38 are received so that the` heads@ ofV the rods will coact `through the cups and through said cushions with the cushions for limiting vrebound of E *l 1.
